However, many scams target people new to the market who may be more susceptible to “get rich quick” schemes because they're unaware of what you can reasonably make taking surveys. It is incredibly uncommon to be offered more than $10 to complete a 20 minute survey. Not that one offering that or more is definitely a scam, it's just important to be cautious. While some experienced and well credited survey takers receive legitimate offers paying that pay big money, if you're new to survey taking you should definitely steer clear of anyone offering you hundreds to complete a survey.
Pinecone asks for your address because your first payout is sent via check to your address. After a few surveys they offer you a paypal option. As far as sending products to test, these are related to the survey you take. I have been with them for a year and they have only sent a few things for me to try out. In the survey, they ask if you would mine trying the product and you can decline. Pinecone is a great company to do surveys with. I highly recommened them!
